摘要： A tubing hanger assembly includes a body having an annular outer surface, a lockdown feature which is located on the body, a load nut which is threadedly connected to the body and has a downward facing load shoulder, and a piston assembly for adjusting a vertical distance between the load shoulder and the lockdown feature. The piston assembly includes an elongated cylinder which is positioned circumferentially around the body axially adjacent the load nut. The cylinder has a first cylinder end which is connected to the body and an open second cylinder end. An elongated piston is slidably received in the cylinder. The piston has a first piston end which is oriented toward the first cylinder end and a second piston end which is configured to extend through the second cylinder end and engage the load nut such that extension of the piston causes the load nut to rotate relative to the body. A seal is positioned between the piston and the cylinder to thereby define a piston chamber between the first cylinder end and the first piston end which is connectable to a source of fluid pressure. In operation of the piston assembly, the piston rotates the load nut to thereby move the load nut axially relative to the body so that the axial distance between the load shoulder and the lockdown feature can be adjusted.

摘要： A wellhead system comprising an outer wellhead housing (54), an inner wellhead member (56), and an annulus therebetween. The inner wellhead member (56), such as a casing hanger, is adapted to land in the outer wellhead housing (54). The outer wellhead housing (54) may comprise a wickers (52) formed in a hardened metal inlay (68). Alternatively, or in addition to the wickers (52) formed in the outer wellhead housing, wickers (50) may be formed in a hardened metal inlay (72) in the inner wellhead member (56). An annular metal seal (64) may be disposed in the annulus and driven into the wickers (52) to seal the annulus between the inner wellhead member (56) and the outer wellhead housing (54) and to axially restrain the seal (64) within the annulus.

摘要： The present disclosure relates to a wellhead assembly 10 having a gas flow control valve 14 with a tubular inlet 24 into which a fluid from a well tube flows, and a gas flow line 16 through which the fluid flows out from the gas flow control valve. An inlet tube 12 has a first end operably coupled to the well tube, and a second end 26 coupled to the inlet 24 of the valve. The inlet has a first groove 30 formed on a surface thereof, and the inlet tube has a second groove 34 formed on a surface thereof. A split lock ring 28 is used which partially rests in, and which is substantially fully compressed into, one of the grooves, when the inlet tube is telescopically coupled to the inlet. The lock ring engages with the other one of the grooves as the two grooves become axially aligned during coupling, to lock the inlet tube to the inlet while permitting rotational movement of the inlet tube relative to the inlet.
